LATCH.

SPECIFICATION forming part of Letters Patent No. 497,863, dated May 23,1893.

Application filed May 12,1892. Renewed April 12, 1893. Serial No.470,112. (No model.)

To all whom it may concern.-

Be it known that I, OLIVER CHRISTIAN, a citizen of the United States,and a resident of Joliet, county of Will and State of Illinois, haveinvented new and useful Improvements in Double Door-Latches, of whichthe following is a specification, reference being had to the annexeddrawings, illustrating theinvention, in which Figure 1 represents theedge of a door, the edges of the supporting blocks and my double latchpivoted thereto and in position as when the door is shut; Fig. 2. ahorizontal section of the door and blocks, taken on aline level with theupper edges of the double latches, a plan of the double latches, ahorizontal section of the central door post and a portion of the edge ofthe opposite door; the assemblage of the parts being in position as whenthe door is closed, and the inner latch is fast on the staple. Fig. 3shows the double latch in position as when one latch is employed to liftthe other from the staple. Figs. 4. and 5 are elevations of the innerends of the two latches.

The nature, construction, application and operation of my double latchWill be fully comprehended by the following detailed description.

A, represents the edge of the door and B. B. are the two blocks securedto the door by bolts E to support the pivot bolts K. M; by which the twolatches C O are pivoted to have an oscillating movement.

At N, the two latches are pivoted together by a bolt passing throughslotted holes in them; whereby the latches have a free movement on thebolts K. M. by which the latches are pivoted to the blocks B. B. asclearly shown at Fig. 2. In order that the top portions of the twolatches inay be at all times on a line when either one is made fast to astaple L a depending standard I is made a part of the inner end of thelatch G and a depending standard .I. is made a part of the inner end ofthe latch C; and both of said standards are enlarged in width below theshanks of the latches; whereby the enlarged parts serve as stops to keepthe top portions of the latches from swinging down out of line.

When the latches are elevated as shown at Fig. 3 to disengage a catch,or staple L the depending standards I. J. come in contact and serve asstops to regulate the lift of the latches; and the shoulder 0 on thestandard J prevents the latches from turning down out of line. Eachlatch is provided with a notch and shoulder V to engage a staple L asshown at Figs. 1 and2; and from the said shoulder outward and upward,are rounded portions to deflect the latches on to the catch. In thesection at Fig. 2 P is a horizontal section of the middle jamb posts;and R represents a portion of the opposite door lapping on to the post.WVhen the door A is constructed to lap also onto the post P the latchesC, 0', must be let into a gain in the edge of the door, of such a depthas will permit the latch C to pass onto the side of the post P as shownat Fig. 2. The staple L is preferable to a pin; in that it has twosupporting prongs. As shown, the staple at Figs. 1 and 2 has an inclinedposition to permit the latch to engage one prong thereof. It is evidentthat if the door A be swung back against the side of the barn, or shed,and a staple be secured to said side, the latch G will engage the stapleand hold the door open; and that either latch C O can be employed todisengage the other latch from a staple.

It has been the custom to employ double shutter fasteners, as shown inPatent No. 473,648. I therefore disclaim double latches which lie in thesame plane, are not pivoted together, do not overlap and are notprovided with depending standards or prongs at their respective innerends to regulate the throw which the latches are to have when open andshut.

That I claim, and desire to secure by Letters Patent of the UnitedStates, is

A door fastener consisting of the two latches G and G, which arefastened separately to blocks and the blocks secured to the flat sidesof the door, and the latches overlapping each other at their innerportions and loosely pivoted together and their inner ends respectivelyprovided with depending standards which regulate the throw of latches asand for the purpose specified.

OLIVER CHRISTIAN.
